INCINERATING PLANT.

Specification of Letters Patent.

Application filed February 12, 1914. Serial No. 818,362.

To all whom it may concern:

Be it known that I, THOMAS E. WASLEY, a citizen of the UnitedStates,-residing at Springfield, in the county of Greene and StateofMissouri, have invented certain new and useful Improvements inInciner-, ating Plants, of which the following is a specification.

My invention relates to an improved incinerating plant or apparatus.

The main object of the invention is to provide a generally-improvedplant or apparatus of the type set forth in Letters Patent of the UnitedStates, for an improved apparatus, for, incinerating refuse material,No. 1,094,503,. issued to me on April 28, 191 1; the plant or apparatusbeing improved particularly with respect to the provision of novelremovable, turnable screens within the main condenser for the productsof combustion, of a more efl'ective form of cover for the drying hopperor chamber, of a valve or closure controlling communication between thedrying chamber and furnace of such construction as not to readily warpor be injuriously alfected by intense heat, of means whereby thecollecting chamber for solid matter may be closed in the event ofstoppage or injury to its drain pipe, so that the operation of the plantwill not be affected, and of means to render the interior of theconductors, collecting chambers or condensers and pump chambersaccessible to facilitate operation,

inspection and cleaning.

In said drawings: Figure 1 is a vertical longitudinal sectional VlBW' ofthe apparatus; Fig. 2 is a horizontal longitudinal sectional view of theapparatus taken on enlarged fragmentary horizontal sectional the line242" o'f -'-Fig. 1; Fig. 3 is an view of the main condenser specificallyillustrating the means whereby the screens employed may be manuallyoperated; Fig. 4: is a transverse sectional view of one of the screendevices employed; Fig. 5 is a vertical sectional view on the line 55 ofFig. 1; Fig. 6 is a vertical sectional view on the line 66 of Fig. 1;Fig. 7 is a plan view of the main condenser showing the power means foroperating the screen devices; Fig. 8 is an enlarged vertical sectionalview through the condenser, and Fig. 9 is a sectional view on the line,9-9 of Fig. 1.

Throughout the various views of the drawings, like reference charactersdesignate like or similar parts.

Referring to the drawings, 1 designates an incinerator chamber inwhichcombustion is supported by a burner 2 therein to which leads an oilfeed'pipe 3. A waterback 4 is associated with the incinerator chamberand hot water therefrom is used at the plant for sanitary purposes, itbeing Patented Apr. ,4, 1916. I

led off through a nipple 5 controlled by a valve 6. Supported on anddirectly over the chamber 1 is a drying chamber or hopper 7 fromwhichleads a distillate conductor pipe 8 to a collecting chamber orcondenser 9 for the distillate or volatile products. Such products asmay settle in this chamber 9 are drawn 03 through a valve-controlledfaucet or nipple 10. From the chamber 1 at its upper end leads aconductor pipe for products of combustion, the pipe being designated 1-1and leading to a condenser chamber 12 for the products of combustion,the

chamber having any desired number of staggered'walls 13, in order thatthe products ofcombustion will follow a tortuous path through thecondenser. At the outlet, the condenser 12 leads'to a stack 14, in theentrance end of which stack is located a nozzle which projects a sprayof water downwardly against the products of combustion, thoroughlywashing the gases before they escape through the stack. Such nozzle orspray is shown at 15. The lower end of the stack 14 communicates with asettling chamber or condenser 16 for the sprayed water and the particlesin suspension therein. This settling chamber 16 is provided with aplurality of staggered baflle walls '17 and with a. pipe 18 throughwhich the settled products in the chamber 16 may be removed. 7

The parts-just described are the equivalent of andpractically the sameas those of the same terms used in my -'*Patent No. 1,094,503, referredto. parts are, of course, employed to render the apparatus complete andadditional parts are also employed, and such latter equivalent andadditional parts will now be described. The cover for the hopper 7 isdesignated 19, and provided with a plurality of notches Other equivalentthrough which extend guide brackets 20. This hopper is adapted to bemoved in a vertical plane, guided by the brackets, and the meansemployed for raising and lowering the hopper may be a suitable cable 21,preferably power actuated, in any suitable manner. The hopper 7 isprovided with a channel 22 which receives a liquid, preferably water,into which liquid extends an annular depending flange 23 of the cover19, when the cover is in closed relation to the hopper, so that theflange 23 in combination with the water in the channel 22 will providean effective water seal for the hopper. The bottom closure for thehopper 7 is in this instance in the form of a bell-valve 24, or thevalve being specifically hollow and frusto-conical. This valve iscarried by a vertically movable rod 25 slidably mounted through astuffing box 26 of the cover 19 and through a suitable bracket 27mounted on said cover. To the rod 25 may be fastened a cable 28 adaptedto be power actuated in order to raise and lower the valve 24.

.The pipe 3 leads from an oil supply tank designated 29 and mounteddirectly on the upper wall of the condenser 13. lVater is supplied tothe water-back 4 through a pipe 30 which leads from a. water supply tank31. \Vater to the channel 22 is supplied by means of a. pipe 32. Theseparts now described, it will be realized, complete an incinerator plantand one substantially as disclosed in my allowed application referredto, this described plant, at the same time, embodying improvements withrespect to the cover for the drying chamber and closure valve therefor.

The additional improvements will now be described: \Vithin the condenser12, intermediate the baflle walls 13 thereof, are suitably mountedscreen devices generally designated 33. These screen devices are shownin Fig. 8 as mounted three in a row. Each screen device consists of aframe in cross section shaped after a cross and having a hub 34 andside-rails 35. The latter being suitably connected to the hub 34 as bymeans of transverse rails 36. The hub 34 and rails 35 are provided withgrooves extending longitudinally thereof and designated 37. In thegrooves 37 are slidably mounted rails 38 of movable screens. have screenmaterial or wire gauze 39 which is fastened to the rails 38. Thesescreens are removable from. the frame comprising the hub 34 and rails 35and 36 by vertical movement upwardly, being adapted to be raised throughopenings 40 provided in the top wall 41 of the condenser 12. The screens3839 have two vertically alined sections pivoted together at 39 so thatwhen removed, the screens may flex intermediate their ends so that thedistance between the wall 41 and floor 64 need not be equal to the Thesescreens length of the screens to permit their removal. The condenser 12should be airtight and to this end the openings 40 are closed bysuitable doors or plates, the latter being pivoted as at 42 for lateralmovement to clear the openings 40 when the screens are removed.Extending longitudinally of the condenser chamber 12 between the bafflewalls 13 thereof and fastened thereto are bearing bars 43 in which, andalso in the top wall 41 of the condenser are turnably mountedcylindrical portions of a shaft 44. On the shaft 44 the frames forsupporting the screens 3839 are fastened. The screen devices are adaptedto be rotated or oscillated continuously or at times in order to removethe soot deposit from the products of combustion passing through the condenser.

In some sizes of plants, it will be practical to shake or oscillate thescreen devices by hand and such a mechanism as will accomplish thisresult is shown in Figs. 2 and 3 of the drawings. Referring to saidfigures, the shafts 44 have rigidly fastened thereto crank arms 45 whichare provided with elongated slots 46, through which pass setscrews 47removably screwed into slidable rods 48 which extend through and beyondthe side walls of the condenser. To the exterior of said'side walls arefastened brackets 49 and pivoted thereto at 50 are bell-crank levers 51,one arm of each of which is provided with an elongated slot 52 throughwhich passes a set-screw 53 removably fastened to the rods 48. The otherarm of the bell-crank lever 51 is fastened by pivots 54 to an operatingrod 55 having thereon an operating handle 56. It will be realized thatwhen the rod 55 is actuated by manual engagement with the handle 56, thebellcranks will cause the rods 48 to turn and accordingly turn and shakethe screen de-- vices. If it is not desired to use this described meansfor manually shaking the screens, the set-screws 47 and 53 can beunscrewed and together with the rods 48 re- -moved from operativeposition. v 1 In large plants-it will be necessary to operate thescreens-by power means and such a means is shown'in Figs. 1, 7 and 8. Tothis end each shaft 44 has keyed or otherwise fastened thereto sprocketwheels 57,

over which pass sprocket chains 58; One

of the shafts 44, however, has merely a' single sprocket wheel 57thereon, but in addition has mounted thereon a'pulley 59.

Thispulley 59 is engaged by a belt 60 driven from a pulley 61 on themainshaft of a suitable motor 62. Upon the motor 62 operating, its motionwill be imparted by means of the belt 60 and pulleys 61 and 59 to thelatter of the shafts 44. Motion of this shaft through the medium of thesprocket wheels and sprocket chains will be the screen devices thereonwill be simultaneously rotated.

The building structure and condensers l2 and 16 and the stack 14 areconstructed preferably from concrete, the structure having a first floor63 and a second floor 64. On the second floor 64 rests the water supplytank 31 and from this floor the material to be incinerated is fed to thehopper 7. A

suitable roof 65 is provided. It will be realized that the floors 63 and64 and roof 65 and end and side walls of the building structure ineffect provide two large rooms, the upper of which is utilizedprincipally for supplying the material to the hopper 7, and the other ofwhich is utilized for-the purp os1e of incinerating and treating themateria The oil fuel is supplied to the tank 29 from an oil reservoir 66located below the floor 63 and forming parts of thebuilding structureproper, through a pipe 67 in connection with a pump 68. The pump properis mounted in a man-hole or chamber 69 of the building proper. A waterreservoir 70 is also provided below the floor 63 and is part of.v thebuilding structure, water being pumped by a pump 71, from thisreservoir.

70 through a pipe 72 leading to the'tank 31 and of which pipe 72, pipe32 forms a continuation. A man-hole 72' into which pipe 72 extends,permits access to the pump and associated parts. The passage of waterthrough the pipe 32, however, is cut off when desired throughthemanipulation of a valve 73. By means of a pump 74 and pipes 75 and76, water is supplied to" the nozzle 15 under pressure for effectivespraying. If

desired, the water could be conducted di-' 7' turnably mounted by a-rod78', a screen 79 normally adapted to jlie'sin a. horizontal plane sothat the smoke passing'through the stack will pass throughv thescreening or gauze of the screen. A crank 80 is fastened to the rod 78and pivoted to the crank is an actuating rod 81. At suitable times therod 81 maybe actuated to shake the screen 79 to remove any depositstherefrom.

' For the urpose of permitting theremoval of material precipitated inthe condenser 12,

and condenser 16, suitable doors 82 are provided. Likewise to permitcleaning of the conductors 8 and 11, removable plugs or theirequivalents 83' are provided: Means are provided whereby the escape ofsettled material from the tank 1'6may be prevented in the event that thepipe 18 becomes clogged or is injured, without stopping the operaisregulated. If it is desired to close the.

chamber 16 against the escape of settled material, it is merelynecessary to turn the hand wheels 88 in such direction as will permitthe valve 84 to lower and have. its lower edge engaged with the floor ofthe tank. The valve 84 in this position, in combination with the guidewalls 85, forms a closed wall or barrier.

Particular attention is called to the fact that the fuel supply tank 29is mounted directly on the topwall 41 of the condenser 12. Thus heatfrom the condenser 12 so acts on the liquid oil within the tank 29 as toconvert it to some extent to a vapor or gas, so that the fuel willreadily flow through the pipe 3 and be readily combustible. To this endthe tank 29 functions as a retort.

In operation the fuel flowing through the burner 2 is ignited, being fedthrough the pipe 3 from the supply tank or retort 29.

With the valve 24 closed against its tapered seat, refuse material, forinstance, garbage, is fed into the hopper 7, the means for feeding thematerial, of course, being immaterial so far as the principle of theinvention is concerned. When the channel 22 is filled passing throughthe pipe 8 into the settling chamber 9 and condensing therein, assistedby air drawn in through pipe 9. The products may be withdrawn from tank9 when desired through the spigots 10. When the material in the hopper,7 has thoroughly driecLthe rod 25 and bell-valve 24' are lowered inorderto uncover the valve seat and thereupon the dried material falls fromthe hopper into the incinerator 1 onto the burner 2. The heat from theburner 2 thoroughly burns or incinerates the previously driedvmaterial,"the products of, combustion escaping or passing from theincinerator 1 through the conductor 11 into the condenser 12. Suchproducts of combustion are acted on by the staggered bafiie walls 13 andby the screens 33, so that the solid particles are precipitated out, thescreens being revolved or oscillated to assist such precipitation, ifdesired. Precipitates in the con denser 12 may be removed through theprovision of doors 82 therein. The products of combustion after passingthrough the condenser 12, are subjected to the action of water underpressure sprayed through the nozzle 15. This water serves to precipitateout any remaining solid particles and also to thoroughly wash the gasesbefore escape through the stack 14. It will be realized that the washedgases before escape pass through the screen 79 whichserves to br ak upthe gases and to precipitate out any possible solid matter notpreviously re moved, so that the remainder of the products escapingthrough the stack 14 will not contain solid matter nor have an obnoxiousodor. As to the water sprayed through the sprayer 15 and the solidparticles contained in suspension therein, this flows into the settlingchamber 16 and may be drawn off through the pipe 18. If access to theinterior of this settling chamber 16 is desired. the same may be hadthrough the medium of the doors 82 thereof. In the event that the pipe18 becomes clogged or needs repairs, the hand-wheels 88 may be adjustedso that the lower edge of the gate-valve 84 will be lowered intocontiguous relation with the floor 63 and in combination with the sides85, prevent the escape of the liquid through this chamber. It will thusbe realized that should the pipe 18 be clogged, it is not necessary tocease operation of the plant while a difliculty is overcome.

It is to be understood that the device described and illustrated merelyforms my present embodiment, in view of which fact, changes in thedetails may be made and are reserved provided they fall within thespirit and scope of the appended claims.
